actually, the most noticeable big difference between 13 and 14 is that 14 is very refined, I mean it starts quicker, loads the GUI quicker, overall the GUI runs smoother. its really an excellent release (except for the possible bugs in x64 version). but x86 is really fast, it's response is almost like the old fritz versions, 11. And so for other difference, I think the Cloud engines are elaborated. anyway no significant new features in 14. but just the impressive smooth GUI.
